AMALG ANIATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 661,995. dated November 20, 1900.

Application filed April 26, 1899. Renewed August 8. 1900. Serial No. 26,796. (No model.)

To all whom it may concern.-

.3e it known that I, THOMAS ROWLAND JOR- DAN, a subject of the Queen of Great Britain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Amalgamating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, and to the letters of reference marked thereon,which forms a part of this specification.

This invention relates to the treatment of auriferous and other ores and sands for extracting therefrom the contained precious metals and is directed to improvements in the amalgamatiug apparatus which forms the subject-matter of United States Patent No. 613,767, granted to me on or about the 8th day of November, 1898.

The nature of the present improvements will be readily comprehended by reference to the following detailed description and to the accon'ipauying drawing,in which isillustrated in vertical central section an amalgamating apparatus embodying my invention.

In the drawing, A A denote uprights or standards,suitably mounted at their base and connected near their upper end by a crossbeam a. Bolted to the cross-beam is a bracket 13, provided with a bearing-sleeve b, in which is journaled the upper end of a verticallydisposed spindle 0. Fixed to the spindle below the sleeve 1) is a bevel-gear (Z, the teeth of which are engaged by the teeth of a bevelpinion d, fixed to a short shaft (1 said shaftbeing journaled in bearings Z) Z), depending from a bracket 15, bolted to the beam at. The shaft d carries a loose pulley d and a fixed pulley d, which has belt connection with a source of power. (Not shown.) The lower end of the spindle is journaled in a bearing 17 provided in the concentrating-pan, which will presently be described.

Fixed to the spindle by means of keys 6 or equivalent devices are sleeves F F, of bronze or other non-corrodible or non-oxidizablc metal. These sleeves, while commonly rotatable with the spindle, are separable one from another, and each sleeve is provided with means for the attachment thereto of one receiving-dish G and one delivery-dish H, whereby each set of dishes, with the connecting-sleeve,is separately detach-ably mounted. The means for attaching the receiving-dish consists of an annular flange f, formed, preferably, integrally with the sleeve near its upper end,screwsf or other devices being driven through the dish-bottom into the flange. At the lower end of the sleeve are vertically-dis posed integral ribs f f against which abuts the bottom of the delivery-dish, screwsf or other devices being employed to attach the delivery-dish to the ribs. The delivery-dishes H are each provided in its bottom with delivcry-outlets h.

Interposed between the spindle and sleeves F is a tube t', which is fixed to the spindle by the keys eand is therefore rotatable with the spindle. The upper end of the tube 11 is tlared to provide a drip-cup t", which receives and retains the surplus oil from the upper bearing for the protection of the amalgamated dishes. The upper end of the spindle is lubricated through the employment of an oi1-cup t and oil-tube t Fixed to the spindle above the uppermost set of dishes is a conical hopper-j, preferably of copper, into which the material is fed and from which it is delivered to the upper receiving-dish through openings j j, provided in its lower end. The material with water is supplied to the hopper through a trough or pipe. (Not shown.)

The apparatus being set in motion through the belt-pulley and bevel-gearing above described, the material deposited in the uppermost receiving-dish is carried by centrifugal action over the edge of said dish and falls into its companion delivery-dish,from when cc it passes through the delivery-outlet h to the next receiving-dish, the degree of concavity of the dish H being such that the material is prevented from passing over its edge and is by its own gravity carried to the base in which the outlet is provided. The material after traversing the series of dishes finds its outlet through tubes 70, which depend from the outlets h and which discharge into the concentrating pan, the construction of which will now be described.

The concentrating-pan, which is lettered L, is provided centrally with a post Z, having a socket Z, in which is fitted the bearing 1) for the lower end of the spindle. Around the post is a well Z into which the tubes 70 discharge, said tubes operating while in motion to agitate the material in the pan. The material passes over the edge of the outer wall of the well Z into a second well Z from thence into a third well l and, finally, discharging through a spout or channel Z the larger, medium, and finer particles being collected, respectively, in the wells Z Z and l and the gangue or waste material passing out through the spout i It will be observed that aside from the general efliciency of the machine due to the provision for bringing the values into intimate and continuous contact with amalgamated surfaces novel features of construction are introduced which greatly facilitate the assemblage of parts and which simplify the apparatus and materially reduce the cost of production. The feature of the depending tubes, which discharge into the pan and operate to agitate the material, likewise contribute to the efficiency of the apparatus and also to its simplicity, inasmuch as separate agitating means are rendered unnecessary.

I claim as my invention- 1. In an amalgamating apparatus, the combination with a vertical spindle having means for its rotation, of a sleeve fixed to the spindle to rotate therewith said sleeve being formed in separable sections each of which is provided toward its upper end with an annular flange and toward its lower end with vertical ribs, a concave receiving-dish fixed to the flange of each section, and a deliverydish of relatively greater concavity having an outlet in its bottom and fixed to the ribs, whereby each of the sets of receiving and delivery dishes is separable from the other sets.

2. In an amalgamating apparatus, the com bination with a vertical spindle and means for rotating the same, of a tube surrounding the spindle having at its upper end a drip'cup for oil, a sleeve surrounding the tube and keyed to it and the spindle, said sleeve being formed inseparable sections, and a receivingdish and delivery-dish fixed to each section.

3. In an amalgamating apparatus, the combinationwith a vertical spindle and means for rotating the same, of a tube surrounding the spindle, a sleeve of the described material surrounding the tube and keyed to the spindle, a hopper near the upper end of the spindle, a series of sets of receiving-dishes and delivery dishes carried by the sleeve, a concentrating-pan below the spindle, and discharge-tubes carried byand leading from the THOMAS ROWLAND JORDAN.
